DOOR-HANGER AND TRACK.

and one which will at the same time efficient-ly perform the service for which it is designed.

To these ends my invention consists of the combination and arrangement of parts hereinafter fully described and illustrated in the accompanying drawings, in which Figure l is a side elevation of my improved door-hanger; Fig. 2, a top-plan of the same; Fig. 3, a section in the line 3 of Fig. 1, showing the hanger in place in atrack and connected to a door; Fig. i, a section through one of the wheels or rollers of the device; Fig. 5, a section in the line 5 of Fig. 4; Fig. 6, a sectional view showing the parts of one of the wheels or rollers before being assembled; Fig. 7 a similar view showing the parts assembled but not upset, and Fig. 8 is a view similar to Fig. 7 showing the parts assembled and upset to form the complete wheel or roller.

Referring to the drawingsA is a track slotted at the bottom to provide for the passage therethrough of the downwardly projecting portions of a door-hanger which receives the door.

B, B are two wheels or rollers, the external configuration of which can readily be perceived from the drawings and a method of manufacture of which will hereafter be described in detail. Each of the wheels or rollers has a central opening or perforation of considerable diameter through which extends a pin, or axle, O, a series of rolls 0 being interposed between the axle and bore of the wheel or roller to reduce friction.

- The hanger is provided with two side-plates riveted to make a solid construction.

brought together in order that the size of the casting thereby supported may be reduced. The axles O are reduced at their ends so that shoulders c are formed, the reduced ends of the axle passing through the side-plates D, and the shoulders resting against the same. After the parts are assembled, the ends of the axles are upset, or y providing the axles with these shoulders the side-plates are spaced the requisite distance apart and, when the ends of the axles are upset and the side-plates thereby clamped firmly against the shoulders, the entire structure is made rigid so that there is no longitudinal play possible between the sideplates with consequent alteration of the angle of the axles with respect to the axis of the frame. Thus, by this simple expedient, a simple, cheap and rigid frame is made of which the side-plates, which are the largest part, can be punched and stamped from sheet-metal with a minimum of expense and inconvenience.

The side-bars D support pivotally between them and below the line of the axle C an inverted Y-shaped casting E which extends through the slot in the track A, and supports-between its furcations a pin 6 upon which is hung a strap E which supports the door, all in accordance with common practice.

Referring now to Figs. 6 to 8, inclusive, the construction of the wheels, or rollers, will be set forth. Each wheel, or roller, is made of three parts. A central tube 5, which is in practice formed up out of sheet metal, and two cup-shaped portions 5 6 The cup shaped portion 5 has a web 5 at rightangles to the axis of the cup, a frusto-conically shaped web 5 and a short outwardly turned flange 5 The cup-shaped portion 72 has exactly the same flanges and webs and in addition thereto a very short cylindrical flange b adapted to slip over the outwardly turned flange b of the cup-shaped portion 6 In assembling the wheel, or roller, the parts are 'set together as illustrated in Fig. 7 and thereupon placedin a die and upset as shown in Fig. 8, the ends of the tube 5 being turned down over the flanges b of the two cup-shaped portions and the cylindrical flange b beingturned down over the flange b of the cup-shaped portion 5 to look the parts firmly together. In this manner an exceedingly strong, light and cheap roller or wheel is provided. This roller is specially advantageous in connection with the form of track: herein illustrated by reason of the fact that the projecting bead formed centrally by the two flanges b and the crimped-over flange extends into the slot of the track, serving to a certain extent to aline the hanger. However, the principal point in combining these two devices is that this particular form of track, that is the track slotted on the bottom, makes it possible to form a wheel or roller out of sheet metal in the strongest and most desirable way. A wheel, or roller, made of sheet-metal and in two parts which meet in a medial line must almost of necessity have a projecting bead which it is very difficult to dispose of except in a track of this particular form. In other words, it is possible with this form of track to build a roller in a form which with other forms of track would be wholly inefficient and useless.

I realize that considerable variation is possible in the details of construction of my improved device, without departing from the spirit of my invention and I do not intend therefore, to limit myself to the specific form herein shown and described.

What I claim as new and desire to secure by Letters Patent is 1. In a device of the character described, a hanger-frame comprislng separated sldeplates adapted to receive wheels or rollers between their ends, a door-supporting pivot loosely confined intermediate the ends of said side-plates, and axles joining said sideplates and having reduced ends to form shoulders bearing against the side-plates, said reduced ends being upset beyond said shoulders, whereby said side-plates are rigidly held in proper spaced relation.

2. In a device of the character described the combination with a track having a central slot in its under surface, of a doorhanger wheel or roller comprising a central tube or bore, and two cup-shaped portions slipped over such central tube or bore, and held in place thereon by upsetting the ends thereof, the said cup-shaped portions meeting medially to form the wheel or roller, and a portion of one being upset over a portion of the other to form a projecting rib, said rib being adapted to seat in the slot of the track.
